Abstract: 579,014. Luminescent materials. CINEMA-TELEVISION, Ltd., and HEAD, R. B. May 24, 1944, No. 10049. [Class 39 (i)] [Also in Group II] Material consisting of particles with linear dimensions ranging from .005 to .05 mms. is separated into two portions, a finer and a coarser, by flowing it on to a clean surface so that the particles adhere thereto, vibrating the surface sufficiently to detach all particles larger than a predetermined size and collecting the finer portion by suitable means. The mechanism described consists of a disc rotating about a horizontal axis having a circular flange, extending horizontally from the periphery of the disc, in which the powder is placed. During rotationthe particles adhere to the flange, are carried up to a point above the bulk of the powder where the larger particles are removed by tapping, e.g. by a trembler bell or by sonic vibrations and fall back into the bulk of the powder. The fine particles still adhering are removed by a collecting device, e.g. brush and tray. The invention is described as relating to luminescent powders. The apparatus may take other forms such as an inclined flat plate or a continuous travelling belt, particles being distributed by a hopper.
